AI Technical Summary

Benefits of technology

"The present invention is a new lighting assembly that includes a high brightness LED in a compact and durable design. The light can operate at extreme temperatures, from 350 feet below sea level to 35,000 feet above sea level. The light can produce light in any visible color, and can also include additional functions such as night vision, infrared, or laser diodes. The flashlight is designed to be interfaced with different equipment and accessories, and is sealed to prevent air and moisture from entering. The technical effects of this invention include a wider range of operational temperatures, a more durable and reliable design, and the ability to be used for a variety of different functions."

Problems solved by technology

Typically, in prior art flashlights manufactured for use underwater, one of the major problems is making the assembly watertight.

Waterproofing the operable components of the switch tends to be particularly troublesome.

After prolonged use, these seals wear and are prone to leakage.

Other parts, such as removable ends for replacement of battery and bulb, also must be sealed and servicing the unit often results in damage to or destruction of the seals.

Further, if these flashlights are configured for use in deep water at depths approaching 350 feet below sea level, they typically require a pressure-equalizing valve to prevent them from imploding from the force of the surrounding environmental pressures.

This problem is further complicated when the same light is also required to operate at high altitudes such as at 35,000 feet above sea level.

Generally, the pressure-equalizing device used for underwater applications will fail at high altitudes and the high altitude device will fail in deep water.

These pressure equalization issues are exacerbated by the fact that the portable flashlights in the prior art typically include a cylindrical housing that encloses the light source, power source, required circuitry, the operable switch element and a relatively large volume of air.

Further, the slide type switch or a spring loaded button type switch of these prior art flashlights require that a portion of the operable components reside on the exterior of the light while another portion is positioned on the interior resulting in a weak point at the interface between these operable elements.
